7.1.4 Generation of the TSP response list file

・The TSP response list file is a file showing the correspondence between the TSP signal recording files
and measurement locations.
・This file must be created according to the 5.3.1 Source position list information (srcinf) format.
・The method used to create this file using the template generation function of HARKTOOL is

Generation Process

１．Start HARKTOOL3 (see 7.1.3Start up), and click the「TSP-ListFile」 button in the
「Select a file type for generation」window.

Figure 7.3: Select a file type for generation

２． When the 「Editing of TSP-ListFile」screen is displayed, as in the Figure 7.4, click the 「Generate Template」
button at the bottom-right corner.

Figure 7.4: Editing of TSP-ListFile

３． When the 「Template generation of TSP-ListFile」screen is displayed, as in the Figure 7.5 is displayed,
input the parameters on this screen and click the 「 Generation Template 」 button.
For each item, see 「Overview of setting items」 below.

Overview of setting items

• Distance[m]

  
  The horizontal distance between the speaker and the microphone.

  Elevation[degree]

  
  The angle of elevation as seen from the microphone in the direction of the speaker.

  Angle[degree]

  
  Ending angle (left), starting angle (right). The TSP signal is recorded in the file at every specified angle, from the starting to the ending angle, in a counterclockwise direction (the interval between angles is specified in the next item). The filenames of these files are added to the template.

  Interval[degree]

  
  The interval between angles

  Filename Template

  
  The place/name of the TSP response recorded file (wav format). String “#DEGREE#” in the filename is replaced by the angle value (3 digits with 0 padding).

  Synchronization Addition Count

  
  The count of consecutive replays of the TSP signal at the time of TSP signal recording.

  Master Impulse file

  
  The filename of the TSP signal containing one cycle used for recording.

  TSP offset[sample]

  
  The number of samples of TSP signals used for recording. Default settings need not be changed.

  Signal Max[amplitude]

  
  The value of the maximum amplitude. Default settings need not be changed.

  Channel List

  
  The channel number to use. If you select a channel, check the box and specify the channel number in comma-delimited format. If you use all channels, the box need not be checked.

  Impulse Response Start Index [sample]

  
  The starting position of the sample used for generating transfer functions. Default settings need not be changed.

  Impulse Response End Index [sample] (This item does not exist on the screen)

  
  The ending position of the sample used for generating transfer functions. If this value is added, transfer functions are generated using the samples from the start to the end index. This item is optional and is manually specified in the text file. This item is used to ignore reflections if, for example, reflection is louder than the direct sound. To add the impulse response end index, specify manually “@end index” after the impulse response start index.
  
• Example To create a transfer function using 1〜100 samples,
  the start index is 「1」, and the end index is manually specified as 「@100」
  
• -0.7071, -0.0000, 0.7071 %%../testdata/tsp/tsp_D180.wav, 1 @100
  -0.7044, -0.0616, 0.7071 %%../testdata/tsp/tsp_D185.wav, 1 @100
  -0.6964, -0.1228, 0.7071 %%../testdata/tsp/tsp_D190.wav, 1 @100
  

４．The templates of TSP-ListFile based on the parameters are displayed on the
「Editing of TSP-ListFile」screen. Click the 「Show Graph」 button on the bottom right,
and verify the parameter settings. (See Figure 7.7).

５．If there is no problem, save the generated files 。Figure 7.6「File」. 「Save」）
